C++ MySql Getting count ids and + 1

Hi, i wish if everyone is having a good day.
However i have an problem in mysql i would like to get the count of ids column in my table and plus 1 to the number how ever when i do like that it types +1 as string for example the result of counting was 3 it will add 3 to 1 like this 31 not 3+1=4 so i don't know how to solve this here's my code :

		String^ constring = L"datasource=...;port=...;username=...;password=..."; // Giving informations to the server
		MySqlConnection^ conDataBase = gcnew MySqlConnection(constring);
		MySqlCommand ^GetCount = gcnew MySqlCommand("Select Count(ID) from newdatabase.my_table;", conDataBase);
		MySqlDataReader^ myReader;
		MySqlCommand ^cmdDataBase;

		try {
			conDataBase->Open();
			myReader = GetCount->ExecuteReader();
			while (myReader->Read()) {
				int Got = myReader->GetInt32(0);
				cmdDataBase = gcnew MySqlCommand("Insert into newdatabase.my_table (ID) Values ('" + Got+1 + "');", conDataBase);//queries
			}
			myReader->Close();
			myReader = cmdDataBase->ExecuteReader();
		}
		catch (Exception ^Ex) {
			MessageBox::Show(Ex->Message);
		}
